How do I remove seat from Kronolog seatost?

The LBS installed it all for me when I bought my bike. I want to swap saddles. I've removed the T25 Torx bolt, and the plastic retaining clip. Still can't get the "female" piece out to remove the seat brackets. Am I missing something? I've scoured the internet for a user manual and there is nothing I could find.

I did what ThundaCrymz recommended, and I was able to get the female side of the bolt and the clamp off, but then I still couldn't get the clamp piece off from the other side. I had to take everything apart and tap the clamp piece from the inside with a hammer. Took a few hits to dislodge it. All this just to lower the nose of the saddle a degree or two. I love the function of the post, but the saddle clamping mechanism is terrible!
